2014 Lexus IS250 F Sport AWDpinterest

Slipped in between the F-tastic back-slap fest that was Lexus’s 2015 Detroit auto show press conference—Hey, it’s the new GS F! Hey, we’re goin’ racing in the RC F!—was a news tidbit about a small engine with big implications for Toyota’s luxury brand. The company plans to spread the turbocharged 2.0-liter four from the NX200t to more models starting this year, a move that would finally bring Lexus’s powertrain offerings closer to par with the European brands with which it competes.

Everyone from BMW to Audi to Mercedes to Lincoln to . . . well, you get it, everyone uses turbocharged four-cylinder engines throughout their lineups, so it makes sense for Lexus to shove its predominantly V-6–powered vehicles into this decade. A Lexus representative wouldn’t tell us which models would receive the turbo four but did say that the small engine would replace the 2.5-liter V-6 in a variety of Lexuses worldwide. In the U.S., that means we can expect the IS250 (the only U.S.-market Lexus that uses the 204-hp 2.5-liter six) to adopt the more-powerful turbo engine, which makes 235 horsepower in the 2015 NX200t.

We’re also told that any Lexus that currently offers engines displacing as little as 3.0 liters could also get the turbo four; it won’t replace the 3.0-liter-plus engine, but rather augment it. Again, no details were given, but it’s safe to assume that Lexus could shove the turbo motor into the U.S.-market ES sedan and possibly even the larger GS to realize some fuel-efficiency gains. Certainly 235 horsepower is enough for the ES, given how the ES300h hybrid makes do with just 220 ponies, and GS competitors such as the Audi A6, BMW 5-series, and Cadillac CTS all utilize 200-to-240-hp turbo fours in their most basic iterations.
